Hey guys I have a Century Arms Zastava Pap M70 that I recently bought. I was told that this gun was originally designed for single stack mags, when Century Arms got there hands on it they milled out the mag well to accept the standard double stack AK mags. Well in doing so they left the single stack bolt and bolt carrier, so you have a problem at times getting the gun to feed a cartridge when pulling the bolt back. When I took mine to the range I had that happen to me twice that day. I also heard that you could change the bolt and carrier out to a standard Yugo M70 bolt and carrier to fix the problem. I was wondering if any of you guys knew if this was true?
